The Directorate of Revenue Intelligence arrested a man with foreign currency and muscle-enhancing steroids worth over three crore rupees at Indira Gandhi International Airport, an official statement issued on Sunday said.

Acting on a tip off, the DRI intercepted the accused on the intervening night of Friday and Saturday when he was going to board a Bangkok-bound Air India flight.

DRI officers recovered foreign currencies, including the Euro and the British Pound, from his possession worth Rs. 1.28 crore, the statement said.

The accused revealed that he worked for a syndicate involved in smuggling of anabolic steroids and the foreign currency he was carrying was for purchasing these, the probe agency said.

In a follow-up search, officers seized many anabolic steroids worth more than Rs. 2 crore, it said.

These steroids are used extensively by athletes and weightlifters in professional tournaments.

There is a growing market for these muscle-enhancing drugs among the youth who are inspired by the bulging biceps of celebrities, the DRI said.

These drugs are have become quite common and are recommended by gyms to their clients who want to improve their body muscles. However, in the long run, they can adversely affect kidney function, it said.

DRI investigators found that the smugglers were sending agents (carriers) to Thailand to bring back the anabolic steroids without declaring them to the customs authorities, the statement said.
